++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ That's not going to be a problem if the flying CG is held in the forward 6" of the CG range. A moderate size tab with moderate amount of travel will be capable of trimming the airplane over the entire speed range. There will be stick forces to trim out with changes in speed, power, flaps, etc., as in an airplane, but they are not an issue if accounted for during construction. Larry Flesner
